UTM & Campaign Tracking

YouTube Shorts generates over 200 billion daily views and 2 billion monthly users, but WooCommerce stores posting Shorts see most of the resulting website traffic reported as Direct in GA4. The YouTube mobile app opens links in its in-app browser, which strips the referrer header. Without UTM parameters on every link in the description and pinned comment, GA4 has no source data and defaults to Direct.

Server-side UTM capture stores attribution permanently as order metadata, immune to browser cookie restrictions and session expiration.
